' INDEX TAB Filed Aug. 29, 1934 INVENTOR ATTO RNEY Patented Oct. 1, 1935 UNITED STATES PATENT OFFICE INDEX TAB a corporation of Ohio Application August 29,

Claims.

This invention relates to improvements in index tabs for use on filing cards and the like, and is particularly directed to a tab of this character incorporating a transparent protective sheath for 5 the index card.

It is the object of this invention to provide an index tab or holder of the above character which limits insertive movement of the tab onto the card in the process of attachment thereof and by the same means defines the sheath for the index slip; which is more readily rernoistened and at the same time is more rigidly and positively attached to the card; and which will remain rigidly attached to the card despite accidental loosening of the side thereof especially adapted for remoistening.

Other objects and further advantages will be more fully apparent from a description of the accompanying drawing, in which:

Figure 1 is a perspective view of the improved index tab.

Figure 2 is a perspective View of the index tab shown in Figure l, showing the same from a diferent angle.

Figure 3 is a perspective view of the filing or separator card, showing the improved tab in position thereon.

Figure 4 is a sectional view taken on line 4 4, Figure 3.

Figure 5 is a general perspective View of a Inodirled form of the improved index tab.

Figure 6 is an enlarged fragmentary perspective view of the modified form of Figure 5.

The index tab as shown in the drawing is fabricated of two strips of material to provide a sheath for the index slip or card, and a pocket or slot engageable over the card margin. The sides of the pocket or slot are extended and form attaching skirts adhesively secured to the respective sides of the card. The structure includes a Wall between the sheath and the pocket defining the sheath and limiting insertion of the tab onto the card margin.

The body of the tab is formed of a doubled strip I0 of relatively heavy celluloid or other transparent material, The walls of the doubled strip are spaced. One side of the strip is longer than the other and constitutes a heavy rigid attaching skirt Il. A second strip I2, which may be formed of any relatively light flexible material is doubled in the same manner as the first strip. This second strip also includes one long side which constitutes an attaching skirt I3 disposed on the opposite side of the tab relative to the first skirt and spaced therefrom.

1934, Serial No. 741,960

This latter strip I2 is nested in the lirst strip a short distance beyond the edge of the short side it of the first strip or body suflicient fo-r attachment. These parts are adhesively secured together under pressure in the process of fabrication at the manufacturing plant. This nested arrangement of the doubled strips provides a transparent sheath or slot I5 for an index slip or card shown at I6. The bend Wall I'I of the inserted strip defines the Width of the sheet or 10 slot providing the bottom wall thereof and. limits and governs the insertion of the tab over the card margin.

It will be apparent that one attaching skirt of the tab is heavy and rigid and is integral with 15 the strip for forming the body of the sheet or the tab, and that the other` skirt is relatively light and exible and is admirably suited to the purpose of remoistening the glue on the skirts. As shown in Figures l and 2, the skirt I3 is extreme- 20 ly flexible and can be lifted to expose the opposing adhesive coated surfaces of the skirts in remoistening operations.

The heavy Celluloid strip attached as one piece on the front of the card and forming the sheath 25 and the principal attaching skirt carries the major portion of the strain. The heavy Celluloid is glued directly to the card and for this reason there is no danger of the tab becoming loosened from the card. With this advantage the tab incorporates the additional advantage of inclusion of a pocket or slot for attachment over the card and an attaching skirt at the rear of the tab which is of light flexible material readily permitting remoistening.

One wall of the sheath may be bowed or curved inwardly against the other wall as at I8 so as to more readily grip the index card between these walls and prevent displacement thereof. In Figures 5 and 6, a modified form of tab is illustrated 40 incorporating a variation in the shape of the tab in that the length of the skirts is increased.

Having described my invention, I claim:

1. An index tab, comprising, a doubled strip of transparent material, one side of which is longer 45 than the other for providing an attaching skirt integral with the strip, and a second doubled strip formed of flexible material and having its bent end inserted between and adhesively secured to the sides of the first strip, the bent portions 50 of said strips spaced apart to provide a sheath for an index slip, one side of said second strip being longer than the other for forming a flexible attaching skirt adjacent to the rst mentioned skirt, said skirts adhesively coated on their inner 55 sides for attachment to the respective opposite sidesof the card.

2, An index tab, comprising, a doubled strip of transparent material, one side of Which is longer than the other for providing an attaching skirt integral with the strip, and a second doubled strip formed of flexible material and having its bent end inserted between and adhesively secured to the sides of the rst strip, the bent portions or" said strips spaced apart to provide a sheath for an index slip, one side of said second strip being longer than the other for forming a iiexible attaching skirt adjacent to the iirst mentioned skirt, said skirts adhesively coated on their inner sides for attachment to the respective opposite sides of the card, the other side of said second strip being short and leaving the inner surface cf the rst mentioned attaching skirt substantially exposed for adhesive attachment directly to a card.

3. An index tab, comprising, a doubled strip of relatively stii transparent material, a doubled strip of relatively flexible material nested and secured in said rst strip, the bends of said strips disposed in spaced relation to form a sheath for an index card, each of said strips having a long side, the long sides of the respective strips oppositely disposed and having their adjacent inner surfaces adhesively coated for attachment to the respective sides of a card.

4. An index tab, comprising, a doubled strip of relatively stiff transparent material, a doubled strip of relatively iiexible material nested and secured in said first strip, the bends of said strips disposed in spaced relation to form a sheath for an index card, said relatively stiff strip having a short side, and said relatively ilexible strip having an adhesively coated skirt extended from said short side.

5. An index tab, comprising, nested doubled strips, one of said strips being formed of ilexible material, each of said strips including one short and one long side, said long sides disposed at opposite sides of the tab and forming spaced attaching skirts, the nested bends of said strips spaced apart to form a sheath for an index slip.
